Description
Use stp loop-protection to enable the loop guard function on the ports.
Use undo stp loop-protection to restore the default.
By default, the loop guard function is disabled.
Configured in Ethernet interface view, the setting takes effect on the interface only.
Configured in Layer 2 aggregate interface view, the setting takes effect only on the aggregate interface.
Configured on a member port in an aggregation group, the setting takes effect only after the port leaves
the aggregation group.
Among loop guard, root guard and edge port settings, only one function (whichever is configured the
earliest) takes effect on a port at the same time.
